PHP namespaces support

two kinds of aliasing or importing: aliasing a class name, and aliasing a namespace name.

Note that for namespaced names (fully qualified namespace names containing

namespace separator, such as <literal>Foo\Bar</literal> as opposed to global names that
|

do not, such as <literal>FooBar</literal>), the leading backslash is unnecessary and not

allowed, as import names

recommended, as import names
|

must be fully qualified, and are not processed relative to the current namespace.
